Explanation:

Histamine is the chemicals that are responsible for the allergic reaction in the body. Antihistamine is the drug that blocks the release of histamine by blocking the histamine receptor.

These drugs are divided into H1 and H2 antihistamine according to the type of receptor it blocks. H1 antihistamine is further divided into 1st generation antihistamine which is having a central effect and 2nd generation antihistamine in which the central effect is less and is used as an antiallergic drug.

Loratadine(Claritin) is commonly used as 2nd generation antihistamine drug therefore the student demonstrates an understanding of the information if they identify loratadine (Claritin) as 2nd generation antihistamine.
